Try to use DataGridView.CellEnter event:

Occurs when the current cell changes in the DataGridView control or when the control receives input focus.

or DataGridView.CellLeave event

Occurs when a cell loses input focus and is no longer the current cell.

Use the keydown or keyup events instead.

Control.KeyPress documentation states:

The KeyPress event is not raised by noncharacter keys; however, the noncharacter keys do raise the KeyDown and KeyUp events.
